Miren STATES JOSEPH KRAUPA, OF ST. LOUIS, MISSOURI.,

GRATE.

SPECIFICATION forming part of Letters Patent No. 252,606, dated January 24, 1882.

Application -tiled October 13, 188i. (Model.) p

To all whom it may concern:

Beit known that I, JOSEPH KRAUPA, a citizen of the United States, residing at 902 South Seventh street, in the city ot' St. Louis and State' of Missouri, have invented certain new and uscful Improvements in Grates, and I do hereby declare the following` to be a full, clear, and exact description of the invention, suoli as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in grates; and it consists in the construction and arrangement of the several parts hereinafter described, and pointed out in the claims.

In the drawings, Figure l is an elevation of a stove. Fig. 2 is a plan ot' a grate and tirepot. Fig. 3 is a cross-section ot lire-pot, with tom ot' saidlopening suitable support for theJ 4o carrier, hereinafter described.

tilted position of grate-sections indicated in `dotted lines. Fig. 4 is a view ot' rear side of tire-pot. Fig. 5 is a partial t'ront view of stove. Fig. 6 is an edge view ot' the latching device, and Fig. 7 is a detached plan view ot' certain details.

a is the outer casing, having fuel-door a and horizontally-elongated opening i2 and ashdoor ai.

b is the tire-pot.

b is an elongated opening in rear of tire-pot, near its bottom.

blis an elongatedopeningin the lire-pot, similar and diametrically opposite to the opening b and directlyin rear of the opening a2 in casing a.

I)3 is a segmental way extended slightly beyond the opening b', and forming with the bot b4 is a way similar to the wab7 b3, and placed alongside the opening b2.

b5 is a carrier placed in the way band made shorterv than the opening. in order thatit may 4'5 have horizontal playin said opening,'and provided with semicircular bearings for the pivoting-rods ot' sections of grate, hereinafter described.

b6 is a carrier placed in the way b4, and similar to the carrier b5. 1

bl is a rack-bar placed alongside and slightly below the way Zrr4 and between it and the casing a. I have shown this rack attached to the part b3; but it will be understood it can be connected directly to tire-pot orto outer casing of in the carrier b, and is extended through the casi'n g a, and .has a slot, d2, in its forward end,

to receive the lug on the operating-handle hereinafter described. d3 is a gear-wheel fixed on the rod d between the casing a, and the tire-pot.

e is a rod ixed to the rear ot' section c2. It bears in carrier b5, and has its end extended over the rack-bar 11T.

c( is a gear-wheel placed on end ot' rod-c, and

.arranged to mesh with and roll from side to side on the rackbar o7, as shown.

e2 is a rod fixed to frontot1 `section c2. It bears in the carrier If, and is extended through the casing a, and its t'ront end is flattened to enter slot in the operating-lever. Y

c3 is a gear-wheel fixed on rod c2 between the re-pot and the casing a, and arranged to mesh with the gear-wheel d3 on the rod rl.

j" is the operating-lever. It has formed in one end a slot, which lits over the flattened end of rod c2, to which it is fastened by a pin. It can thus be swung out freely without aft'ecting the grates, while an upward or downward movement of the lever tilts both the sections of the grate. This is accomplished by the gearwheel on rod c2 meshing with the gear-wheel on rod d, thus tilting the sections toward or away from each other as the operating-lever is raised or lowered. It will be seen thegearwheel c on end of rod e, meshing with the rackbar lf' as the grates are tilted, will roll to left or right, according to the direction ot' the tilting,and take the carrier with it, thus giving an IOO additional disturbance to the coals in thelireand arranged in proper position to be engaged by the latch hereinafter described.

f3 is a bar tixed on front of stove, and having formed in its front a slot to receive the leverf when it is swung in horizontally against the side of the stove.

f5f5 are lugs formed at top and bottom of barfa, extended outward. The lever can he operated between these lugs, th ns giving a limited rockingmovementtothegrate-sections.

f4 is a drop-latch having formed through it an opening, through which passes a pin, by which itis connected to the barff. The opening in the drop-latch is somewhat elongated7 so that thelatch can be raised or lowered. The latch has formed on its end a hook arranged to catch in the hook on the leverf and hold the lever till it is released by raising the latch.

Having thus described my invention, what I claim, and'desire to secure by Letters Patent, 1s

1. A grate composed ot" the two grate-sections provided with front and rear pivot-bars bearing in sliding carriers placed in suitable ways, both front bars and on`e of the rear bars beingprovided with gear-wheels, the gearwheels on front bars being arranged to mesh together, and the gear-wheel on rear pivot-bar being arranged to engage a rack-bar placed alongside thc way, supporting the carrier on which said bar rests, substantially as set forth.

2. The combination of the tire-pot having formed through it horizontal openings with carriers lnade shorter than and placed in said openings, and provided with bearings to reeeive thepivot-bars ofthe grate-sections,where by a lateral motion may be given the gratesections, substantially as set forth.

3. In a stove, the combination of a lire-pot formed with openings through it, carriers made shorter than and placed and supported in said openings, and ways placed alongside and pro vided with bearing for the grate-sections, the tilting grate-sections, and means for'operating, snbstantiall y as set l'orth.

4. The combination ot'the grate-sections, the' frontpivot bars of which are extended through the casing of the stove, the one having the operating-lever hinged to it, the said lever having a lug placed thereon and arranged to enter a slot formed in the end of the other front pivot-bar when the grates are in a horizontal Aposition and firmly lock the grates in such po-v JOSEPH KRAUPA.
